No. They don't.
And any piercer who tells you otherwise is lying to you.
A daith piercing is not a medical procedure. It's not performed by anyone in the medical field. Calling it a "migraine cure" is a sales pitch — and a dishonest one at that. Think about it this way: if a piercing genuinely cured migraines, your GP would have learned how to perform it somewhere in their six years of medical school. They didn't.
That said, I do have clients who swear their daith piercing helped with their migraines. I also have clients who saw no improvement at all. And clients who felt relief for a few months, then the migraines came back once the piercing fully healed. So what's actually going on?
The pressure point theory
Close to where we pierce — but not exactly on it — there is a pressure point associated with blood pressure regulation. High blood pressure can be a trigger for migraines. This pressure point sits at the bottom of the helix crus, where it meets the conch of the ear.
A daith piercing is placed at the top of the helix crus, where there's a small soft spot. If we were to pierce at the actual pressure point — the bottom of the crus — it would essentially be a surface piercing through the conch. Extremely painful, and your jewelry would constantly flip outward instead of sitting nicely in the ear.

Why it might feel like it helps
In the first weeks of healing, the piercing causes swelling. Depending on your anatomy, that swelling might put some pressure near the pressure point — and for some people, that seems to reduce migraine frequency. Once the piercing heals and the swelling goes down, that pressure disappears. Sometimes the jewelry itself still applies enough pressure to maintain some effect. Sometimes it doesn't.
Worth remembering: we're piercers. We pierce through skin. We don't install anything that applies controlled pressure to a specific point — that's acupressure, and we're not trained in it. The fact that swelling occasionally mimics that effect is coincidence, not science.
So should you get it?
If you want a daith piercing because you love the way it looks — absolutely. It's a beautiful placement and I'd love to pierce it for you.
If you're getting it specifically to cure your migraines, I'd advise against it. The chances of it actually working are unpredictable, and you'd be making a permanent decision based on a theory that has never been proven.
Get it because it's beautiful. Not because someone on TikTok said it fixed their headaches.
